To all whom it may'c'oncern:

Be. it known that I, GEORGE H. Covn, a citizen of the UnitedStates, residing at Roxbury, in the county of Suflolk and- State of Massachusetts, h'ave'invented an Improve-v Binding-Post Attachments, ofwhich the fol owing description, in connection with the accompanying drawings, is a specification, like characters on the drawings re resenting like part s. 1 c Iy invention is an im rovement on the binding-post attachment s own in my apl'plication, Serial No. 303,986, filed Marc 7 1906, in which the securing nut or means Was shown'as a centrally-perforated and threaded nut fastened securely between the opposite 7 arms or spring members, so that the application and removal of the attachment to the usual threaded st of the battery required that the attac ent should be screwed around like; a usual nut, whereas 1n my present improvement the nut or securing means clamping the attac simply engages the threads at the opposite sides of the threaded 0st in a latera ly-removable manner, so t at the rotary screw motion and the delay thereof are avoided.

in carryin out my invention I provideopposite threa -,enga 'ing means for det'achab ent ontothe threaded post of the battery or other electrical appae' ratus or device, so that when the' arms are in wire-clamped engagement the attachment is thereby held automatically in fixed engage ment on the post and when the arms arereleased from wire-holding position the attach-, ment.is thereby automatically released from said fixed position, In the accompanying drawings, Figure 1 is a perspective view of'a usual dry battery provided with my attachment, shown in operative wire-holding position, Fig. 2 is a perspective" view showing the attachment in wire-released position. .Fig. 3 shows the attachment in side elevation, partly broken away; and F i 4 is a vertical sectional view of a sh htly-diiferent construction.

Whi e my attachment is capable of a wide variety of embodiments within the spirit and scope of my claims, as hereinafter set forth,

1t preferably consists in its preferred form of a strip of spring metal bent in U shape to form opposite spring-arms 1 2, having tongues 3 4, the latter being downwardly bent, as shown, (see Fig. 3,) and the tongues Specification of Letters Patent.

3 being spaced apart to embrace said tongue 4 and being upwardlybent, said tongues having grooves or. hollows for receiving and re taming a wire w when sprung past each other to the position shown in Fig. 1 The U- shaped metal strip is perforated at 5 to fit over a usual threaded screw or binding-post 6, and. the, opposite projecting spring members 1 2 are provided on their inner sides with embracing jaws or securing means, which may be secured thereto in any desired manner, but preferably consist of pleces 7 8, struck in from the metal of said arms themselves, as clearly shown, said jaws-7 8 projecting approximately perpendicularly to the arms 1 an "2' and being of such a length that when the arms are pinched together for retaining a Wire the jaws 7 8 are thereby caused to bite into or grip the post 6, and hence au tomatically clamp the attachment fixedly in circuit-closing o erative position on the battery- 0st 6. When the wire w is released,

there y permitting the tongues 3 and 4' to spring apart to the position shown in Fig. 2,

' the arms 1 and 2 automatically withdrawthe plication. For all practical purposes it is usually suificient that the jaws 7 and 8 should ent ma be applied or removed in-.

have simply one threador engaging edge to fit into the threads of the post'6, although they may have a wider engaging surface prov ded with more extensive threads for interlooking with a greater extent of threaded surface of the post 6, if desired, the same as in my previous application. Such a constructlon is shown in Fig. 4, which I consider aspbstantial equivalent of Fig. 3 in its essentla s. v

Having described -my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. A battery binding-post attachment,
